I drive a lot more than I should. Mostly rental cars or one of my 3 F150’s. First off, I don’t like trucks or SUV’s. So despite how pleasant my V8 F150 is, I much prefer to be in a big sedan with a big engine, or if I want to be sporty, a late model Mustang GT (which is a great highway car)
the OP’s experience mirrors mine. I like big sedans with a V8. And,,,, sorry, a Prius is downright annoying, harsh and loud on epic trips. There really is something pleasant about a conventional V8 that becomes evident after a long trip.
manufacturers can silence and smooth out all sorts of engines, but it’s not the same.
